Key Features & Specs:
FactionFab Axle Back Exhausts are designed for Subaru WRX and STI owners who want a better exhaust sound, cleaner rear-end styling, and a simple bolt-on upgrade without replacing the full exhaust system. An axle-back is one of the easiest ways to change the tone and look of the car, making it a popular option for drivers who want more presence without going into a full cat-back setup.
Each FactionFab axle-back exhaust is built for vehicle-specific fitment and is designed to replace the factory rear muffler section. With 304 stainless steel construction, hand TIG-welded quality, and multiple tip finish options like polished, burnt, and black, these exhausts give Subaru owners a clean appearance upgrade with a more aggressive sound and a direct-fit installation.
